炼油污水处理厂二沉出水中溶解性有机物组分分析
Characterization of four fractions of dissolved organic matters in secondary effluent of refinery wastewater treatment plant
摘要
Abstract
The dissolved organic matter(DOM)in the effluent from the secondary effluent of a refinery wastewater treatment plant was separated by MCX/MAX extraction column,and four sub-components including hydrophobic acidic component(HOA),hydrophobic alkaline component(HOB),hydrophobic neutral component(HON)and hydrophilic substance(HIS)were obtained.3D-EEM and ESI FT-ICR MS were used to analyze each component.The results showed that specific fluorescence peaks of phenolic substances and petroleum substances existed in the refined wastewater,there were more compounds in HOA component,which mainly was CHOS substances;less substances were detected in HOB component,which mainly was O3S1 substances,and more CHOS,CHON and CHO substances were observed in HON component.This study makes an in-depth analysis of DOM in the effluent of refined wastewater,providing a reference for treatment process optimization and environmental impact assessment of external drainage of refinery wastewater.关键词
